NFKB1 and schizophrenia: When considered as one homogenous group, people with schizophrenia have ~20–30% higher levels of RelA, cRel and NF-κB1 transcript and >80% higher levels of NF-κB2 transcript in the dorsolateral PFC compared to non-schizophrenic controls, while levels of RelB mRNA do not differ between the two groups [11].
